Description

Steel wire loop fixing device

The utility model relates to an orthopedic surgical instrument, which is applied to a comminuted fracture case, and successfully achieves the purpose of functional resetting and firm fixation of the displaced fracture block under the condition of closed reduction and minimally invasive internal fixation operation, and solves the closed condition. Fracture fragments cannot be ideally fixed and fixed. Background technique

There are no special instruments (or equipment) for wire fixation of fractured pieces (including temporary fixation and permanent fixation). In the past, in order to achieve the purpose of functional reduction and effective fixation of broken bone pieces, it is necessary to cut at least 4 - 5 cm of skin incision in the part where the fragments are located, so that the wire can be directly placed by hand to be circumferentially fixed, basically in direct vision. The next operation, in this way, will inevitably cause unnecessary "sub-injury (mainly nourishing blood vessel damage)" in soft tissue (including periosteum), which in turn affects fracture healing and even causes fracture non-healing. However, under the premise of open reduction surgery, the presence of such secondary damage is acceptable.

The length of the plate is generally determined to be able to fix three locking screws at the entire backbone. The figure is not shown).

Step 2: Determine the location of the cut skin in the range of fractures that need to be fixed and fixed, and try to overlap the predetermined plate fixation screw pedicles, which can reduce repeated incisions to reduce soft tissue damage. The skin incision is about lcm long.

Step 3: First rotate the first lance handle extension piece 1442 of the first wire guiding device 1 to a position opposite to the first sleeve handle extension piece 1242, the first sleeve handle opening 1244 and the first lance handle The openings 1444 are opposite each other while the first outer cylinder opening 126 and the first inner cylinder opening 148 are not aligned.

Step 8: Continue with the outer sleeve 32 to continue counterclockwise rotation, while pulling and tightening the cerclage wire, pay attention to the appropriate force. After the cerclage wire is knotted, the pulling force is gradually relaxed, so that the wire knot of the entangled wire can be erected to reduce the stimulation of the surrounding soft tissue.

Step 9: Rotate the inner core 34 while keeping the outer sleeve 32 relatively fixed (clockwise), taking care to prevent the locking pin 348 from coming out when passing through the groove 3464, cutting the tail end of the entangled wire and withdrawing the instrument.

Step 10: If there are other fracture blocks that need to be reset, as in the case of operation, wait until all important bone fractures have been treated before fixing the locking plate.

The utility model has the following beneficial effects:

2. The wire tightening and twisting device 3 can be easily extended into the deep part of the limb. Under the premise of not requiring direct vision, the small fracture can be used to reach the deep fracture piece, and the fixed wire is circumsed, screwed and twisted.
